Sensors are not anything new to us. They are in use since the past few decades. The new sensors; however, are a wireless variety and staples for modern aircrafts. They facilitate the constant monitoring of aircraft internals and are low in both cost and weight. Airplanes are all about tallying between mind-bending figures and they determine how safe an aircraft is flying. They must be kept under constant check to ensure it is within the safe parameters, with every rule and condition kept under constant reviews and improvements. The latest technologies and scientific knowledge makes it an existing form of transport that’s safer than before. Monitoring overall aircraft condition costs lesser and less time-consuming. It’s just a fifth of the overall aircraft-related operating costs approximately. The use of wired sensors in engine(s), gearboxes, airframes and the fuel-flow structures monitored bumped up the bill, but wireless sensors discard the unnecessary burden. The wires vanished and the WSN (wireless sensor network) took control. These smart sensors use radio-interface for intra-communication and are free from the chief constraints that wired sensors pose, like cumbersome deployment and costly installations, lots of time...in short, they remove major impediments vanish, including those that make installation a tough job on the moving parts of the engine. Wireless sensors bring down costs. You don’t need any more the special structures to let the wire pass through. Installing airplane sensors don’t need any more wiring costs to deal with, nor any data wiring layout, thus saving a great deal of time, effort and energy. They are lower in weight (cables are heavy) and are greatly flexible about where you put them. Some of them also sense heat and stress and this can bring improvements in aircraft designing and maintenance. Withstanding higher accelerations or extremely low/high temperatures need a communication system that’s resilient to radio interferences and jamming and also low on energy consumption. They need to be highly compact and slim in design and must accurately sync to sensor measurements between different nodes. Concurrent engineering approaches gave us that and aeronautical electronics designed a communication protocol that constantly adapts to an aircraft’s multiple operational phases. Highly integrated electronics make the current wireless aircraft sensor systems much smaller than before. Careful component selection and embedded implementation also play a part in it. There are several types of Aircraft Level Sensors used in modern aircraft cockpits. Right from temperature sensors (measure the temperature of various engine components, including cylinder heads, exhausts, engine oil, fuel and hydraulic fluid) to liquid level sensors mounted in thermo-wells (for reservoirs, tanks, sumps and gearboxes) and working on single point or multiple point interface elements connected to onboard display units and flow sensors displaying the flow rate of aviation fuel or engine oil. It is mounted within a thermo-well like liquid-level sensors and also connects to Digital EGT Gauges. The three other are the RPM Sensor (indicates either absolute or differential pressures), proximity sensors (detects if the landing gear is extended or retracted) and the RPM sensors (plugs into the magneto to provide feedbacks to the RPM display) and together, they provide critical information to the pilots that can save their day. The pilots can concentrate on flying when every reading is Green. Moreover, they let you know when it is not. The sensors have a direct bearing on the safety of an aircraft!

The engine needs an even and steady flow of fuel to run without hiccups or knockings to keep up its overall performance. The flow of aviation fuel is displayed by the fuel flow indicator. Fuel flow indicators measure less or excess fuel flow and helps to check fuel wastage caused by rich-burn engines. It works with aid from Aircraft Engine Sensors, located behind the fuel filter, in combination with MAP (manifold air pressure). It not just saves money but also keeps the engine cleaner; which means, a less maintenance cost. The JPI’s Aircraft Fuel Flow Indicator uses modern sensors that connect to a modern, Digital EGT Gauge. This gauge is installed in the cockpit. It is highly accurate; as accurate as digital. The latter are also manufactured by JP Instruments. Rich-of-Peak is a technique that runs the aircraft engine with an excess of fuel in the cylinder. This is done to keep the engines cooler, but on the flip side, the carbon builds up on the exhaust faster. It also increases cylinder pressure. But with Lean-of-Peak or LoP, the piston pushes longer, gentler and slower. The peak cylinder pressure now develops later than the top-dead-centre position than with RoP, at a time when the piston has travelled further along its downward stroke. So, a hammer blow changes into a gentle push. The engine shall operate at exactly the same horse power but with a 35°F lower cylinder head temperature. This equates to a better speed, lesser fuel flow and a longer life for the engine. The less fuel consumption occurs since LoP makes all fuel in the cylinder get used. There remains nothing to blow back and contaminate the oil. This means lesser carbon deposits and savings on the maintenance. And contrary to the belief that LoP is good for low power settings, it helps to obtain 75% of the engine’s power without using extra fuel. The fuel flow indicators help you detect that. For, without measuring fuel flow, you must rely on approximations; either about the flight time or about the fuel flow rate for each phase of flight. JPI’s aircraft fuel flow indicator uses small turbine transducers to measure the fuel flowing into the engine. It rotates faster with higher fuel flows RPM Sensor and slower with the lean ones. They generate pulses this way and measure the gallons used per hour with high resolution. These fuel flow indicators can also keep track of the fuel used if you log the total fuel amount into them right at the beginning. Additionally, you will also be able to detect various other parameters. There are indicator lights to show the information currently displayed and mode of operations that can be selected with front panel operating buttons. An EGT Gauge is also known as an exhaust gas temperature gauge. It is generally used to help with the monitoring of temperatures in the exhaust of a vehicle. Because high temperatures are dangerous for vehicles, it is key to have the best EGT gauges possible. When choosing the best EGT gauges, it is important to buy them from a company that you can trust. This is why choosing J.P. Instruments will be the best bet for you. J.P. Instruments History J.P. Instruments has a huge history in the world of engineering and technology.

An aircraft owner or a pilot goes through many pre flight procedures in order to ensure that him and or his passengers are safe after take- off. One of the biggest insurances that you can afford for your aircraft is investing in a high end EGT & CHT gauge. Both of which can save you thousands of dollars on the engine maintenance and damage. But before understanding how they can save you money and be your insurance from damage, there needs to be an understanding of what they provide for the owner. EGT Gauge This gauge holds full responsibility in displaying how much exhaust heat your piston engine gives off. All in all, it measures the heat energy that is wasted during an exhaust stroke in the moment that the cylinder is under lowered stress. Normally on the display of the actual gauge you may find three lights (Red, Green, Yellow). Those indicate precaution stages with red obviously meaning to be prepared for the worst. In a piston aircraft it holds the responsibility for the mixture of fuel and air to give the best performance/range of the engine. CHT Gauge Unlike the EG Gauge, the CHT holds measure for heat energy that is wasted during a power stroke when the cylinder undergoes maximum stress. It is very essential to limit the CHT in order to ensure cylinder longevity. There are several other responsibilities that this gauge holds: • Losses of Friction • Radiation • A Conduction to Air The One and One Together Solution In comparison to a vehicle, aircraft maintenance is quite pricey. There is no really set in stone insurance that can save you from huge engine expense either. But what can play the key role is installing an EGT Probe & CHT gauge in your aircraft. All functions of the engine can be monitored and maintained at the correct moment, thus allowing you to save money and be insured that the long activity of the cylinder will be extended. Other benefits include: • Early Warnings • Maintenances • Abnormal Combustion Events • Low/High Pressure Identification • Temperature • Oil Temperature All in all both Fuel Gauges are used to prevent and monitor multi functions of the aircrafts engine and cylinders. Since everything depends on each other, you need a system that can ensure you that your aircraft will be safe to fly and can be depended upon. In addition, a great gauge system will act as your insurance that will help cut maintenance cost and save you money. Expensive damage can usually occur when there is not proper maintenance of when things when they need to get done, but when the warning comes at the right time there should not be any excuse of why you would not be prepared. |
